What Job would use...

[hynaku]

Maybe a freelancer class. Didn't they use double blade staff. Also think mime uses the same weapon to.

Judges

Judge Magisters wield paired weapons, one short, and one long; separate, these weapons act like single-handed weapons, conjoined, they act akin to a double-ended polearm, with both blades' edges facing outwards rather than a cyclical parallel. One example is of Judge Gabranth, whose weaponry comprises of the Chaos Blade and the Highway Star.

It have to be a tank right
:^)

Cloud = ff7 = Dark knight
Squall = ff8 = Gun breaker
Zidane = ff9 = ????

In a twist, yes, it could be a tank

[Hasrat]

Hmm... the weapon makes me think of the Berserker Dresssphere from FFX-2. But I don't really remember what that Job's gimmick was.

Berserker's gimmick was... berserk. It was the auto-pilot job. Auto-regen plus all the counterattacks coupled with the speed and power boost from berserk made it the trash killer. Not even sure where you get the connection with the twinblade dealie; Berserker was all beasts and claws.

Fighter?

Although 8-bit theatre would have me rather fighter use swordchucks.

My impression I always got of Zidane was that he was a thief/rogue. He had the trademark steal/mug abilities and dual wielded daggers most of the time, but also used polearms. Steiner filled the roll of tank in that game, though I can't remember if he had taunt type abilities. But he definitely had the highest defense.

I think Steiner had Provoke, but don't quote me on that. But aside from that, he was the tankiest of the bunch for sure. I think his Trance quadroupled his attack power the higher or lower his health was (again, don't quote, i can't recall).

On topic; I couldn't really see anything outside of Theif using that kind of weapon, but their playstyle would probably be too similar to Ninja. Eithe way, I'm fully biased because of my love for IX and I would LOVE to see theif swords get some action ingame.

To be honest, I used to joke in the past that the winged Judge from FFXII Revenant Wings (see image below) should have had a double edged weapon like Gabranth's.

FFIX's characters all had classic FF jobs assigned to them; Zidane was a Thief, and Steiner was a Knight. Steiner didn't have Provoke, but he had the highest HP and Def of the playable characters, and Trance straight-up tripled his attack power, regardless of health. That being said, he still had some abilities from other jobs, like Darkside from Dark Knight and the Break abilities and Iai Strike from Samurai, so it wasn't strictly a one-to-one deal. Admittedly, I had to look this up on the FF wiki, as it's been a long time since I played IX, and I couldn't remember if Steiner had Provoke or not, either.

Personally, I only really see two ways of the double-blade staffs being integrated: either they give them to DRG, as they're not dissimilar enough from a lot of the current lance animations to merit an entirely new job, or they give combining daggers to NIN, somewhat like what Zidane does in Dissidia (wields dual daggers that can combine at the hilt to make a pseudo-staff weapon), and add new abilities that would have animations similar to Zidane's attacks. Maybe drawing upon the Rogue characters again for that?

How about Runefencer/Runeknight?

It's a medium often requested job and people often start argueing about longswords beeing to similar to DRK's greatswords.

I'd be on board with that.
Zidane did have his magic attacks via Dyne after all.

[Jonnycbad]

FFXIV's DRK is a fusion of Rune Fencer and Dark Knight, just as Warrior is a fusion of Viking/Berserker/Warrior jobs. Rune Fencer specialized in great-swords and mitigating magic damage, which is a theme that DRK specialized in 3.0 (and less so in 4.0 due to the homogenization of tanks, but still there). Moreover, activating Blood Weapon creates red runes on your blade for a few moments during activation.

Also, Zidane used Dyne spells during trance, which awakens his true powers as a Genome from Terra. All his Dyne spells utilize Terran runes and script, and were abilities imbued in him at birth that he forgot about and only realized when he's under huge emotional stress.

That said, the swallow, or eku, is a weapon that originated from Okinawa and resemble and oar. They were only used for self defense but were basically double-sided naginata. I could see them being a weapon for a class that specializes in Staff/Pole in general. Kind of like Raijin in FF8 or any of the melee staves used in FFXI.
